After growing up with Horo constantly visiting despite how much his dad complains about him, Men develops a huge crush on Horo, not realizing his dad and Horo are in love (but refuse to do anything about it). Men tries to seduce Horo, only to learn Horo would only ever want Ren.
Feel free to take this to FULL PORN. MEN IS THE SLUTTIEST LITTLE SLUT JUST LIKE HIS DAD AND HE DESERVES TO RIDE HORO TOO GODDAMMIT
Maybe Ren even walks in on them?? I dunno
